Juan wants to know the cross-sectional area of a circular pipe, He measures the diameter
which he finds, to the nearest millimeter, to be 5 centimeters,
To find the area of the circle, Juan uses the formula A =Tuple where A is the wea of the
circle and r is its radius, He uses 3.14 for a, What value doen Juan ger for the wea of the
circle? Make sure you include your units,
Answer: The area is 19.625 cm^2
Step-by-step explanation:
For the area of a circle, the equation is:
A = pi*r^2
where pi = 3.14 and r is the radius of the circle, and the radius is half the diameter.
We have that the diameter is 5 cm, then the radius is:
r = 5cm/2 = 2.5 cm
Then the area is
A = 3.14*(2.5cm)^2 = 19.625 cm^2
Answer:
[tex]19.63 cm^2[/tex]
Step-by-step explanation:
Diameter of the Cross-Sectional Area=5 cm
Radius =Diameter/2
Therefore, Radius of the Cross-Sectional Area of the Cylindrical Pipe =5/2=2.5cm.
[tex]\text{Area of a circle, A=} \pi r^2\\=3.14*2.5^2\\=19.625\\$Area of the circle \approx 19.63 cm^2 $ (to the nearest millimeter)[/tex]
The Cross-Sectional Area of the cylindrical pipe is [tex]19.63 cm^2[/tex].

OmZE = cos 3
0 mZE = cos(4:6
mZE = tan-13
mZE = tan-1 4,6
Answer:m<E=tan-1(3/4.6)
Step-by-step explanation:
The triangle is an illustration of a right triangle
The equation that could be used to find angle E is [tex]E = \tan^{-1}(\frac{3}{4.6})[/tex]
To calculate angle E, we make use of the following tangent ratio

The right square pyramid represented below has a
base edge of 6 inches and a height of 5 inches.
in
What is the volume in cubic inches of the
pyramid?
HINT: 1. The base is a square, therefore all sides are the same.
2. Multiply all the numbers and then divide by 3 since the formula is V = 1/3 Bh.
Final answer:
The volume of the pyramid can be found using the formula V = (1/3) * B * h, where B is the area of the base and h is the height of the pyramid. Plugging in the given values, the volume is 60 cubic inches.
Explanation:
To find the volume of a square pyramid, you can use the formula V = (1/3) * B * h, where V represents the volume, B represents the area of the base, and h represents the height of the pyramid.
In this case, the base is a square, so the area of the base is side * side. Since the base edge is 6 inches, the area of the base is 6 * 6 = 36 square inches.
Plugging in the values for B and h into the formula, we get V = (1/3) * 36 * 5 = 60 cubic inches.

Option A or Option B
How much more does it cost than the other option? __
(b) For what number of miles driven do the two options cost the same? __
If Milan drives less than this amount, which option costs less?
Option A or Option B
Answer:
If she drives the car 150 miles, option A costs more. It'll cost $30 more.
The options cost the same if she drives 75 miles. If she drives less than 75 miles, option A costs less.
The required answer for (a) if Milan drives car 150 miles then Option A costs more $30 than Option B
Also the answer for (b) is the two Options costs same at 150 miles

In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6997 subjects randomly selected from an online group involved with ears. There were 12961296 surveys returned. Use a 0.01 significance level to test the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.
Answer:
[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]
[tex]p_v =P(z<-3.137)=0.0009[/tex]
Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%
Step-by-step explanation:
Data given
n=6997 represent the random sample taken
X=1296 represent the returned surveys
[tex]\hat p=\frac{1296}{6997}=0.185[/tex] estimated proportion of returned surveys
[tex]p_o=0.2[/tex] is the value that we want to test
z would represent the statistic (variable of interest)
[tex]p_v[/tex] represent the p value (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to test the claim that the true proportion of returned surveys is less than 0.2.:
Null hypothesis:[tex]p\geq 0.2[/tex]
Alternative hypothesis:[tex]p < 0.2[/tex]
The statistic is given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Calculate the statistic
Since we have all the info required we can replace in formula (1) like this:
[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]
Statistical decision
The next step would be calculate the p value for this test.
Since is a left tailed test the p value would be:
[tex]p_v =P(z<-3.137)=0.0009[/tex]
Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%
We formulate a null and alternative hypothesis about the survey return rate. Then, given the returned survey and total survey counts, we calculate a sample proportion, standard deviation, and a z-score. Using this z-score, we compute a p-value, which is checked against the given significance level to make a decision about the hypothesis.
Explanation:In this scenario, we are interested in whether the cell phone survey return rate is less than 20%. So we can set our null hypothesis (H0) as: The return rate is 20% or more, and our alternative hypothesis (Ha) as: The return rate is less than 20%.
Given that 12961296 surveys were returned out of 6997, we can compute the sample proportion (p). Then, we calculate the standard deviation (sd) of the sampling distribution of the proportion (assuming H0 is true - i.e., the proportion in the population is 20%).
Using this sd and the sample proportion, we can calculate the z-score. The p-value would be the probability of getting a z-score as extreme as what we got, assuming H0 is true. If the p-value is less than the significance level (0.01), we would reject the null hypothesis. If it's higher, we fail to reject the null.
Note: Due to the likely typographical error in the given number of returned surveys, the precise computation cannot be done here.

The foreign language teachers at school collected data about the numbers of students in their classes. Two languages, French and Spanish, are taught in both 8th grade and 9th grade. The teachers created the table shown. Approximately what percent of all students in a foreign language class are 9th graders taking Spanish?
A) 56%
B) 52%
C) 27%
D) 21%
Answer:
27%
Step-by-step explanation:
Add the number of students: 87+86+71+92= 336
Divide the number of 9th grade Spanish students by the total number of students: 92÷336= 0.27
Times by 100 to get a percentage: 27%
Final answer:
To find the percentage of 9th graders taking Spanish compared to all students in foreign language classes, add the counts from all classes to find the total, then divide the number of 9th grade Spanish students by this total and multiply by 100.
Explanation:
To determine the percent of all students in a foreign language class that are 9th graders taking Spanish, we would need the total number of students taking foreign languages and the number of those who are 9th graders taking Spanish. Let's assume we have the following numbers in our data table:
8th grade French students
9th grade French students
8th grade Spanish students
9th grade Spanish students
Add the numbers of all the students together to find the total. Then, divide the number of 9th grade Spanish students by the total and multiply by 100 to get the percentage.
For example, if there are 100 students in total and 27 of them are 9th graders taking Spanish, the calculation would be:
(27 / 100) * 100% = 27%

Given:
The number 12 is the geometric mean between 3 and a number x.
We need to determine the value of x.
Value of x:
Since, we know that the geometric mean is the square root of the product of two numbers.
Hence, we have;
[tex]Geometric \ mean= \sqrt{a \times b}[/tex]
where a and b are two positive numbers.
Substituting Geometric mean = 12, a = 3 and b = x, we get;
[tex]12= \sqrt{3 \times x}[/tex]
Squaring on both sides, we get;
[tex]12^2=3 \times x[/tex]
[tex]144=3\times x[/tex]
Dividing both sides of the equation by 3, we have;
[tex]48=x[/tex]
Thus, the value of x is 48.

A cylinder has a volume of 8,792 cubic units. If the height of the cylinder is 7 units, which of the following represents the radius of the cylinder?
Answer:
I think its 20 units I could be wrong though
Step-by-step explanation:
The radius of the cylinder = 19.99 units
What is the volume of the cylinder?[tex]V=\pi r^{2} h[/tex], where 'r' is the radius and 'h' is the height of the cylinder.
For given example,
the height of the cylinder (h) = 7 units
the volume of the cylinder (V) = 8792 cubic units
Using the formula for the volume of the cylinder,
⇒ V = π × r² × h
⇒ 8792 = π × r² × 7
⇒ r² = 8792/(7 × π)
⇒ r² = 399.8
⇒ r = 19.99 units
